O. WILLIAM MORLEY, OF TARRYTGWN, NEW YORK.

Letters Patent No. 94,629, dated September 7, 1869.

IMPROVED EDG-ING-TOOL FOR vI-IARITESS-MAKERS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom fit may conce/ra:

Be it known that I, O. WILLIAM MoRLEY, of Tarrytown, in the county of Testchesten and State of New York, have invented a new and improved EdgingJIool and Ido hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being, had to the accompanying drawing, forming part of this specification.

This invention relates to new and useful improvements in tools for edging or scarfing leather, in the process of 4making harness, and for similar purposes, whereby accuracy in the width and depth of cut, as well as a great saving of time, is secured.

The invention consists in connecting"adjustable guides with the knife, for regulating the cut, and also in making the cutting-blade detachable, as will be hereinafter described.

In the accompanying plate of drawing- Figure l represents a longitudinal side-view of the tool, and

Figure 2, a view of the under side of the same.

Similar letters of reference indicate corresponding parts.

A is the handle, which is connected with a shank which supports the detachable cutting-blade and the gauges for regulating the cut, both in width and depth.V

B is the shank.

C is a roller in the end of the bar D, for gauging the depth of the cut. Q

This bar is pivoted to the shank B, near the handle A, as seen at e.

Its position in relation to the knife is governed by the finger-screw f.

Beneath the bar there is a small spring, g, which bears against the bar with a constant pressure.

When in use, this roller or guide C revolves on the leather near to the fixed guide h, on the shank B.'

For' gauging the width of cut, an adjustable guide, t', whose shank j is a spring, is placed on the back of the knife.

This guide is attached to the shank B, as seen at k.

It is moved or adjusted on the back of the knife by means of the finger-screw L.

In iig. 1 the guide-end of the shank B is'seen in section through the line :v-x of fig. 2, in order-to show the position ofthe knife and the screw by which it is fastened.

m is the knife, and

'a is the sectional portion of the shank B, to which the knife is fastened by the screw O.

,y p'is a slot in the shank, which allows the knife to be moved forwardlas it is diminished in length by grinding.

In the edging-tools heretofore used by harnessmakers the cutting-edge or knife is not removable, consequently it is very difficult to keep it sharp.

In my improvement the knife is readily detached for grindingr or sharpening.

When the gauges are set for any desired width and depth of cut, the tool may be used with a certainty that the edging will be done with perfect accuracy and dispatch.

Having thus described my invention,

What I claim as new, and desire to secure by Letters Patent, is-

- 1. In combination with an edging-tool for harnessmakers, and for edging leather generally, making the cutting-knife removable, substantially as and for the purposes described.

2. The adjustable guides 'i and C, for gauging the Width and depth ofthe cut of the knife, when arranged, and operating substantially as described, and for the purposes set forth.

3. In combination with an edging-tool, one or two adjustable guides or gauges, for governing either 'the depth or width of the out of the knife, substantially as described.

The above specification of my invention, signed by Witnesses FRANK BLooKLEY, E. GREENE COLLINS.
